UNITED STATES GEORGE WIESMANN,

OF CINCINNATI, OHIO.

STEEL-WELDING COMPOUND.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed February 26, 1906. Serial No. 303.076.

To all whom, it may concern.-

Be it known that I, GEORGE WIEsMANN, a citizen of the United States,residing at Cincinnati, in the county of Hamilton and State of Ohio,have invented a new and useful Improvement in Steel-l/Velding Compounds,of which the following is a specification.

This invention relates to a compound for Welding steel; and the objectof the invention is a Welding compound capable of standing a veryintense heat.

This compound consists of saltpeter, borax, a mineral dust, eithermarble or brick dust preferred, and iron scales.

The various ingredients are cooked or boiled until finely pulverized,and the compound is then ready for use. A compound consisting of theseingredients in the following-named proportions has been tested and foundsatisfactory: one ounce of saltpeter, six; ounces of borax, four ouncesof brickdust, and six ounces of iron scales. If desired, the brick-dustcan be mixed with marble-dust; but the brick-dust by itself has beenfound satisfactory and is more readily 1 obtainable in most localities.When steel has been burned through being brought to more than a cherryheat, it can be Welded by using the above-described compound equally asWell as unburned steel.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent, is-

1. A Welding compound consisting of saltpeter, boraX, a mineral dust,and iron scales.

2. A Welding compound consisting of saltpeter, boraX, brick and marbledust and iron scales.

3. A Welding compound consisting of six parts of boraX, six parts ofiron scales, four \parts of mineral dust, and one part of saltpeter, allin a pulverized condition. GEORGE WIESMANN.
